[PATCH 14/54] dt-bindings: hwmon: Add IIO HWMON binding
From: Maxime Ripard <hidden>
Date: 2021-07-21 14:05:00
Also in:
linux-devicetree, linux-hwmon
Subsystem:
hardware monitoring, open firmware and flattened device tree bindings, the rest · Maintainers:

Even though we had the iio-hwmon driver for some time and a number of boards using it already, we never had a binding for it. Let's add it based on what the driver expects and the boards are providing.
